There is another principle, also, which I will mention: the various articles should have _constant_ places, that is, they should not be changed from day to day.

By this means you soon remember where every thing belongs, and you can put away your things much more easily every night than if you had every night to arrange them in a new way.

Now will you look into your desks, and tell me whether they are, on these three principles, well arranged ?" The boys of most schools, where this subject had not been regularly attended to, would nearly all answer in the negative.
"I will allow you, then, some time to-day, fifteen minutes to arrange your desks, and I hope you will try to keep them in good order hereafter.

A few days hence I shall examine them.

If any of you wish for assistance or advice from me in putting them in order, I shall be happy to render it." By such a plan, which will occupy but little more time than the irritating and useless scolding which I supposed in the other case, how much more will be accomplished.
